Christina Haack is enjoying time with her fiancé.

The 38-year-old reality star was recently spotted sporting her brand new rock on her finger while soaking up some one-on-one time with her beau Joshua Hall in Cabo San Lucas, Mexico. She also wore a pink bikini while Hall showed off his various tattoos by wearing only a pair of blue swim trunks.

The "Flip or Flop" star has been dating Hall, who works at a real estate firm in Texas, for a few months, first stirring rumors of a romance back in July.

She was previously married twice: Once to her "Flip or Flop" co-star Tarek El Moussa from 2009-2018 and again to fellow reality star Ant Anstead, whom she wed in 2018. They finalized their divorce earlier this year.

The divorced couple shares two children: 10-year-old daughter Taylor and 6-year-old son Brayden. Haack also shares a 2-year-old son, Hudson, with Anstead.

Young offered up sentiments similar to her groom-to-be's as well.

When exactly Hall popped the question is unclear, and rumors of engagement began to circulate last month when she reportedly posted – then deleted – a photo of her wearing a sparkler to her social media account.
